My wife had her One S charging over night, and this morning around 9am unplugged it and went to work. Near the end of the day around 6pm, it notified that the battery was low, and shortly after that powered itself off. She says she barely used the phone, just to send a few texts, and that wifi had been off since she left the house.
I checked the native battery usage app in ICS and took a screenshot:
It looks like something just mysteriously drained the battery constantly since the phone was unplugged. As you can tell from the screenshot GPS and Wifi were both off, and the screen was rarely on. I'm not sure what it means by "Awake", but at some point during the day the phone became awake and stayed that way, which accelerated the battery drain.
Does anybody know any more ways I can debug this or find out what happened?
